共检定了７株金葡液的生产菌种——金黄色葡萄球菌，经过形态、生化反应、血浆凝固酶活性及对抗菌素的敏感性等９项检查，发现除ＸＩＥ７５００４４菌种对四环素敏感，另６株菌对四环素不敏感这一差别外，其它检查结果全部一致。从而摸清楚了现有金葡液生产用菌种的保存情况，对指导生产和加强管理有重要参考价值。 Seven Staphylococcus aureus strains were tested - Staphylococcus aureus. After nine tests including morphological, biochemical reaction, plasma coagulase activity and antibiotic susceptibility, it was found that except XIE750044 strain was sensitive to tetracycline, 6 strains of tetracycline is not sensitive to the difference, the other test results are the same. So as to find out the preservation of the existing strain of fermented grapefruit production, which has important reference value for guiding production and strengthening management.
